问题 It is important that she ______ a record of everything she does in the experiment.
选项 A、keep
B、must keep
C、keeps
D、will keep
答案 A
解析 本句为虚拟语气在主语从句中的典型用法。在It is necessary/important/strange/natural (这类形容词还有advisable，appropriate，desirable，essential等)，及It is required/suggested/desired/proposed，it is a pity等结构中，that从句要用虚拟语气，即“should+动词原形”，should通常可以省略。例如：It is vital that we(should)be present，我们出席是至关重要的。
